TYPE-WRITING MACHINE Patented .time 1e, 190s.

Application led March 12,1808. Serial No. 420,669.

To all whom it may concern.'

Be it knwn that I, EMIL L. PFUNDER, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have inventedcertain new and useful Improvements in Type-Writing Machines, of which the following is a speciiication.

This invention relates to the adj ustable-'devices upon typewriting machines, which regulate the widths of the right and left hand side margins on the written sheet, and determine the point at which .the bell is rung. andf the keys locked, etc. margin gages, adjustable independentlyof each other, are usually provided upon every writing machine; but heretofore in certain types of machines, as for` instance the wellother for substantially the entire length of the line of writing, so that either'orboth gages may be used at either extreme ofV the travel of the carriage.

In carrying out'my improvements I extend arocking frame along the carriage, but mounted upon the 'framework at the front of the machine. stantially the entire width of the machine. It is constructed to operate. the bell-ringing and key-locking devices. I provide a tappet upon the carria e, and arrange an, interponent between t e tappeti and therocking-l frame, the interponent carried upon a slide or margin gage" block. The interponent has a nose that is engaged by the carriage tapet, and in turn it operates the rockingirame. The latter-is not adjustable across the machine, but owing to the adjustability of the interponent, the rocking frame may be made to act atv substantially all points of the carriage travel.

' ably mounted u on a rack bar, which may be cylindrical; an upon the same rack bar, I mounta slide or gage to control the Width of the margin at the left hand side of the written sheet. i

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is Two of such devices or This frame extends for sub-` Said slide or block is prefera'. front elevationof the margin-controlling mechanism of' an Underwood front strike writing machine. Fig. 2 is a front elevation artly in seetion, showing the saine devices. ig. 3 isa sectional plan thereof. Fig. 4 is a sectional side elevation of the front part, oi' the paper carriage and the margin-gage mechansm. Fig. 5 is a side elevation, and Fig. 6 a plan of the slide, block or margin gage which controls the return of the carriage. Fig. 7 is a sectionalfside elevation, and Fig. 8 a front sectional elevation Yto show the margin-gage which controls the bell-ringing and key-locking devices.. The front bar 1 of the carriage has rolls 2 tov `run upon a track formed upon a bar 4` supported' upon standards 5 at 'the front of the'machine. Upon the carriage is fixed an index 6 to coperate with a scale 7 upon said bar. The margin gages are mounted upon a iixed cylindrical rod 8 mounted by its ends in the op osite standards '5, and formed on its lower ront face with notches or teeth 9 at letter-space intervals, to be engaged by the dogs of the margin gages. hel bel rin in and ke -locking devices are contro le `by ua slide 1() having a longitudinal bore to t upon said rod or rack bar 8, and having its upper face 11 adapted to fit or bear lightly against the inclined under side of the bar or rail 4, Fig. 4, to prevent turning of the slide about the cylinder rack bar. An index 12 u on the slide coperates with the scale 7 to Iketermine the position of ringing the bell or locking the keys. The slide is adjusted along the bar by meansof a handle 13, which is secured upon a dog 14 having at its inner end one or more teeth 15 to engage the rack teeth.

- Just beneath the slide 10 is 'a rocking frame or bar 16 'ournaled at its ends upon screws 17 threaded into the standards 5. Secured to the left hand` end of, the rocking frame 1.6:by means of screws 18, and pendent therefrom. is the usual bell-riny ing and ke locking arm 19,-which is cause by the 'roc ing of the frame 16 to perform its usual functions in the usual manner.

The rocking frame 16 is caused to operate by means of a tappet 2O secured upon the front of the carriage by means of a screw 21. Said operation is performed by means' of an interponent v22 having a nose 23 engageable by the tappet and pivoted upon a shoulder screw 24, tapped into the adjustable slide 10.

30 to press ownthe rocking bar 16, is made usua gressedan interval, the second projection 26 operator may then 65 works in a recess 50 formed in the The tap et 20 has one projection 25 for ringing the ell, a deeper projection 26 for loc ing the keys, and a-second key-(lookin .pro-

' The yinter onent '22', which hasV a bearingv in two partsfcne part carry-ing said nose 23, and the other'part 31 pivoted u on the'sc'rew' 24, said parts securedtogether which passthrough longitudine slots' 33 yin" towards or" away from .hence relativeljlfto the dog teeth 15,' which engage the'z rac 8's0'as to 'cause the opera# 20 tion of the-member 19 to occur at thev desired'point in the letter-spacing movement of thecarriagey.v`v

It willbe understood that as the carriage is letter-feeding'towards the left,'Fi 8, t e

25 tappet rj'ectlon 25 first engages t e nose 23 to. epress the interponent 22- and the .frame 16, thereby effectlng enou 'h forward swin of the arm 19 to ring.' the ell in the.

manner. After the ,carriage has proengages the noseI 23 and forces the interponent 22 down still farther, thereby rocking the bar 16 and the member 19 ,sufliciently to lock the keys in the well known manner. The ress the button 28 as usual, to release the eys, and after.printing a few more letters, the third projection 27 j engages the nose 23 to lock the keys for the second time. The carriage is finally arrested by tlie engagement of the left hand end of the tappet 20 with a stop 34projecting rearwardly from the left hand end of the slide 10. The latter may be adjusted for substantially the entire length of the run of the'carriage, or to any portion of the rack bar 8 not blocked by the other margin gage.

The width of the right hand margin on the age'is controlled by a second slide 35, which 1s substantially similar to the slide 10, except that the interponent and the stop 34 -are omitted. This slide or gage 35 has a rear- 'wardly projecting stop 36 .to engage a stop 37 pivoted at 38 u onthe carriage and having a key 39.' vAt i 6, it will be seen that the dog 40 may be pu led forward by its knob or handle 41 to release its teeth 42 on the rack 8, said dog being mounted in a guide. way 43 formed in the slide 35, and retained y by wide headed screws 44 tapped into the un- 50 der side of the slide with threads overhangin the opening 43. A keeper-plate 45 is secured 'by screws 46 upon the front ofthe slide and, perforated at 47 to form a guide for a stem 48 upon the dog. A compression s ring 49 og bythe bell-ringing and key-locking devices o ated b said rocking frame, a plate' xedv e carriage and having tappets to en, gage successively said cam during the move-- *side of the stem 48, and bears at itsouterend against the 4plate 45, its inner -end extending into a hole 51 in the dog. The construction 'of the doge, spring andl appurtenances is the 'sem' f 01` 30'0 slides 10 and 35i 4"It" willbe seen that either of the mar ingages ,may be moved for the entire lengt of the;fotherfthereohplandj'hence that oth or 'either-'may be brought intofoperation at any portion yof,jtheiravel ofthe' carriage.
